Abstract

The electrical current generated by heart creates not only electric potential but also a magnetic field. In this paper, we have designed the multiplexing data acquisition system for multi-channel bio-magnetic signal measurement. The system consists of VXI rack that is organized MUX and AD board, industrial rack that is mounted single board computer and DSP board. This system enables to real time monitoring of multi-channel data simultaneously. The number of channel could be increased simply added each module and firmware could be upgraded easily using host port interface of DSP.
